Our CM-1700 is designed to test a person, their wrist strap and subsequent attachment to a reliable ground on continual basis. Should the wrist strap or connection to the technician fail the CM-1700 provides both a visual and audible alarm. The unit may be adjusted for impedance and contains an on/off switch. Each unit is provided with a NIST calibration certificate.

Our CM-1701 is designed to test a person, their wrist strap AND a workstation ESD matís attachment to a reliable ground source on a continual, ongoing basis. Should the Technician or mats connection to ground fail the CM-1701 provides an immediate visual and audible alarm. The unit may be adjusted for impedance and contains an on/off switch. Each unit is provided with a NIST calibration certificate.

Our CM-1702 is designed to test TWO Technicians', their wrist straps, their impedance and continuity to a reliable ground on a continual, on an ongoing basis. Should the Technicianís primary grounding fail the CM-1702 provides an immediate visual and audible alarm. The unit may be adjusted for impedance and resistivity limits and contains an on/off switch. Each unit is provided with a NIST calibration certificate. This unit is not designed for use in testing ESD matting.
